I claim:

1. A fastener device of the class described comprising, in combination, a head portion, an attaching portion disposed in spaced relation to said head, and an integral yieldable connection between said head portion and said attaching portion permitting relative movement toward and away from each other, and said attaching portion being provided with a notch extending inwardly from one edge thereof to permit a screwing action of .the attaching portion through an aperture in a structure to be engaged by the fastener device.

2. A fastener device of the class described comprising, in combination, a head portion, an attaching portion disposed in spaced relation to said head, and an integral yieldable connection between said head portion and said attaching portion permitting relative movement toward and away from each other, said attaching portion being provided with a notch extending inwardly from one edge thereof to permit a screwing action of the attaching portion through an aperture in a structure to be engaged by the fastener device, and said attaching portion, at opposite sides of said notch, being bent in opposite directions to facilitate the screwing action.

3. A fastener device of the class described com prising, in combination, a head portion, an attaching portion disposed in spaced relation to said head, and an integral yieldable connection between said head portion and said attaching portion permitting relative movement toward and away from each other, and said attaching portion being provided with a notch extending inwardly from one edge thereof to permit a screwing action of the attaching portion through an aperture in a structure to be engaged by the fastener device, the said connection being formed from the material cut out to form the notch in the attaching portion and extending from `about the center of the attaching portion to one edge of the head portion.

4. A fastener device of the class described formed from a single piece of sheet metal and having ahead portion arched in cross-section to provide resiliency thereto, an attaching portion located beneath said head portion in spaced relation thereto and having a notch to permit insertion of the tattaching portion through an aperture by a rotary motion, and a yieldable connection extending between and securing the said portions together in such a manner as to permit movement of one toward and away from the other.`

5. A fastener device of the class described formed from a single piece of sheet metal and having a rectangular shaped head portion arched lengthwise in cross-section to provide resiliency thereto, a generally circular shaped attaching portion located beneath said head portion in spaced relation thereto and having a notch to permit insertion of the attaching portion through an aperture by a rotory motion, and a yieldable connection formed from the material of the attaching portion cut out to form said notch and extending between and securing the said portions together in such a manner as to permit movement of one toward and away from the other,and said attaching portion at opposite sides of said notch .being bent out of the plane of the remainder of the attaching portion to facilitate attachment and detachment of the fastener device.

6. A fastener device of the class described comprising, in combination, a head portion, an attaching portion overlying said head in substantially parallel relation thereto, an integral yieldable connection extending from one edge of said head towards a point within the periphery thereof and in spaced relation thereto, and said connection joining said attaching portion .at a point within the peripheral edge of said attaching portion thereby permitting parallel movement of one portion toward and away from the other.
